Requests are identified as being for a cacheable object or a non-cacheable object according to information included in a Uniform Resource Locator (URL) associated with the object. For example, the URL may include a port designation for requests for cacheable objects (e. g. , images and the like). Thus, a request may be recognized as being for a cacheable or non-cacheable object according to the port on which the request is made. In some cases, requests for non-cacheable objects may be made on port. A router may be thus configured to recognize a request as being for a cacheable object or a non-cacheable object according to a port on which the request is received and redirect it to a cache as appropriate.

In the face of data loss on connections between a content source and a content consumer, additional connections therebetween are opened. These additional connections are preferably opened between the content source and a proxy disposed between the content source and the content consumer. The proxy may then seam together data streams received from the content source across the additional connections in a recording on a computer-readable medium. The seamed stream may be constructed by filling in information gaps in any of the data streams received from the content source with content derived from others of the data streams received from the content source. This derivation may be made on the basis of identifying characteristics (e. g. , packet contents) of packets from each of the data streams received from the content source.

In the face of unacceptable data loss on connections between a content source and a content consumer, additional connections therebetween are opened. These additional connections are preferably opened between the content source and a proxy disposed between the content source and the content consumer. The proxy may then seam together data streams received from the content source across the additional connections before passing a resultant seamed stream to the content consumer. The seamed stream may be constructed by filling in information gaps in any of the data streams received from the content source with content derived from others of the data streams received from the content source. This derivation may be made on the basis of identifying characteristics (e. g. , packet sequence numbers and/or time stamps) common throughout each of the data streams received from the content source.
